There are two unholy words which Oracle sales people usually avoid when talking
about RAC: functional partitioning. Functional partitioning means that each RAC
node has a separate and specialized function and is mostly dealing with one 
part 
the database. That is still the best way of organizing RAC system. Also, with
several cluster nodes, the private connection becomes crucial. With 64 nodes,
N-cube like communication structure must be in place, so that each node is 
reachable through the fixed number of hops.
